页面由JSP改造成thymeleaf,系统没有报页面有错误,于是启动,访问对应页面时,报出一长串异常,核心是org.thymeleaf.exceptions.TemplateProcessingException: Could not parse as expression: "{.......}",刚开始遇到这个异常,也是一时手足无措,前后台各种找BUG,还是老样子,最后上网搜索,才知道,一些有JSP页面的写法,在thymeleaf是行不通的,按JSP的写法,thymeleaf渲染错误,下面是我原来的写法:
columns:[[{
field: "examTime",
title: "检测时间",
width: 140,
align: "center",
formatter: function(val){
if(val){
return val.substring(0,19);
}
return val;
}
}, {
field: "tempC",
title: "体温",
width: 140,
align: "center"
}, {
field: "descript",
title: "风险描述",
width: 250,
align: "center",
formatter: function(val, row, idx){
if(val && row.level>0){
return "<label title=\"" + val + "\" style=\"color: #FF0000;\">" +
val + "</label>";
}
return "";
}
}]]
因为[[…]]之间的表达式在thymeleaf被认为是内联表达式,所以无法正常渲染,页面也就访问不了了,正确的写法是把columns后面的[分行写,不要写在一行里,如下:
columns:[
[
{
field: "examTime",
title: "检测时间",
width: 140,
align: "center",
formatter: function(val){
if(val){
return val.substring(0,19);
}
return val;
}
}, {
field: "tempC",
title: "体温",
width: 140,
align: "center"
}, {
field: "descript",
title: "风险描述",
width: 250,
align: "center",
formatter: function(val, row, idx){
if(val && row.level>0){
return "<label title=\"" + val + "\" style=\"color: #FF0000;\">"
+ val + "</label>";
}
return "";
}
}
]
]
